Maxim Integrated DS2432P+T Secure EEPROM

The Maxim Integrated DS2432P+T is a high-security, 1Kb protected EEPROM with SHA-1 Engine that provides a robust solution for secure data storage. This device integrates memory and security features into a small, reliable package, making it an ideal choice for applications that require stringent data protection and authenticity verification.

Key Features

• Secure Memory: The DS2432P+T offers 1024 bits of EEPROM memory partitioned into four pages of 256 bits, with each page further subdivided into four blocks of 64 bits. This organization allows for flexible data management and protection schemes.
• SHA-1 Engine: The onboard SHA-1 hash function ensures that stored data is protected against tampering. This cryptographic algorithm generates a 160-bit hash value, which can be used for data integrity checks and authentication purposes.
• Challenge and Response Authentication: The device supports a challenge-and-response authentication system, which uses the SHA-1 engine to verify the authenticity of the DS2432P+T and its stored data.
• Write Protection: Each memory page can be individually write-protected or put into EPROM-emulation mode, where the memory behaves like a write-once read-many memory to prevent accidental or malicious data changes.
• High Reliability: The EEPROM is designed for a minimum of 100,000 write cycles and a data retention of over 10 years, ensuring long-term data integrity.
• Compact Form Factor: The DS2432P+T comes in a space-saving TSOC-6 package, making it suitable for applications with limited PCB space.

Applications

The versatile nature of the DS2432P+T allows it to be used across various industries and applications that demand secure data storage and protection, such as:

• Medical device authentication
• Accessory or consumable identification
• Secure data storage for sensitive applications
• Aftermarket management
• System and device integrity checks

The DS2432P+T from Maxim Integrated stands out as a powerful solution for designers and engineers looking to incorporate secure data storage and authentication into their systems, without compromising on space or reliability.
